But Ann Arbor school officials maintain that allowing guns in schools would make it impossible for educators to ensure the community that they are providing a safe learning environment for children.

"How can we possibly determine the intention of a gun-carrier on campus, to sort out the ‘good’ guys from those with malicious intent?" Ann Arbor Superintendent Jeanice Smith said in a statement following the board vote. "The presence of guns in schools runs contrary to everything we are wired for in education, and is counterproductive to maintaining a rich, productive, and healthy learning environment for our children.”

"No person in possession of a dangerous weapon will be allowed to remain on property owned or leased by [the district] at any time when students are at school, en route to or from school or at a school..."

"A dangerous weapon shall include a firearm (including a starter gun or pistol) or any device which will or is designed to or may readily be converted to expel a projectile by the action of an explosive, any destructive device or any explosive, incendiary, or poison gas bomb, grenade, rocket having a propellant charge of more than four ounces, missile having an explosive or incendiary charge of more than one-quarter ounce, mine or similar device; a dagger, dirk, stiletto, knife with a blade over three inches in length, or pocket knife opened by a mechanical device, an iron bar or brass knuckles or, any other weapon as set forth in 18 USC&921. Also, any electronic device that inflicts or causes pain or suffering is likewise considered a weapon.*
